Lake Index Monitoring
Lake Index Monitoring involves observing, measuring, and recording environmental data as
well as collecting water samples. Lake Indix Monitoirng is done away from the shoreline,
and therefore requires the use of a boat, canoe, or kayak. Environmental data that is
recorded is the same as those recorded by Baseline Monitors and includes parameters such
as air & water temperature, wind conditions, wildlife presence, Secchi depth, and an overall
perception of the condition of the water body. During each sampling event, two water
samples are collected and sent to the State Health Lab in Pierre for analysis. Parameters
such as, ammonia, nitrates, total Kjeldahl nitrogen, and total phosphorous are analyzed.
Locations are sampled twice a month between April and October.
